Participants in the Antarctic Search for Meteorites (ANSMET) program have just concluded their latest expedition to Antarctica, searching for space rock samples that are preserved there. They return home with no less than 300 meteorite samples, making this one of the most successful missions of this sort to date.

A team of geologists analyzing a puzzling rock sample discovered that it was made up of a type of crystal that had never before been encountered in nature. Scientists know all there is to know about this material, but only because they created it in the lab. Now, they hypothesize that the rock is in fact a meteorite.... |

Researchers at the Washington University in St. Louis are currently investigating the origins of a pallasite meteorite that was identified by space rock hunter Karl Aston back in 2009. The object belongs to an extremely rare category of meteorites, of which only 20 are known in the entire US.
This particular one t... |

A new scientific study suggests that meteorites should not be regarded exclusively as a threat to our planet. It may very well be that – in the early days of the solar system – the space rock brought the ingredients of life, or maybe even life itself, to Earth.
Researchers were able to establish that ... |

A team of experts recently determined that some of the basic building blocks of deoxyribonucleic acid (DNA), the basic building blocks of life, may have originated in meteorites that were produced in space. This finding has tremendous implications for theories on the origins of life here on Earth.The research lends a... |

New studies appear to suggest that either all or part of our planet's atmosphere did not originate within the Earth – as studies suggest – but was rather brought here by space impactors such as comets and asteroids. A new research proposes a little tweak to these ideas. University of Manchester inves... |

Molecules without which life would have not appeared and developed on Earth appear to be produced in large quantities on asteroids. The space rock then spread their “products” via meteorites through solar systems, and on nearby planets. The same thing happened on Earth. Even now, molecules produced by the... |

The geological record shows that our planet experienced a period of low temperatures some 12,900 years ago. This time frame has been dubbed the Ice Age, and experts have believed for a long time that it was caused by a meteorite, or other space rock, slamming into Earth. However, new evidence appear to indicate that ... |
